  • the present invention relates to an actuating device with an electromotive rotary drive and more particularly to the actuating element, which can be driven rotatably about an axis of rotation between a first end position and a second end position and further acted upon out of the first end position by a spring.
  • actuating devices of this type it is known to operate the actuating element by means of the electromotive rotary drive counter to the force of the spring and over the entire actuating travel between the first and second end positions.
  • a permanent operation of the electromotive actuating drive is also required.
  • a permanent supply of current and therefore a permanent expenditure of energy is also consequently necessary.
  • the activating electronics of the actuating drive is also operated permanently, the load on these electronics, particularly as a result of heating, is high and necessitates higher-grade electrical and electronic components, with the result that the activation electronics are costly.
  • the actuating device serves for regulating the operation of a further device, such as, for example, for regulating the stream of a cooling liquid in a coolant circuit of the internal combustion engine for a motor vehicle, it is necessary that, in the event of a failure of the actuating device, a sufficient cooling liquid stream continues to be maintained, so that the internal combustion engine can be operated further, at least in an emergency running mode.
  • An object of the present invention is to provide an actuating device of the type initially mentioned above, which, in the event of a failure of its electromotive rotary drive, ensures that an intermediate position of the actuating element is assumed.
  • the instant drive would operate with a saving of energy and further have a simple and cost-effective construction.
  • the present electromotive actuating drive comprises a reversing drive.
  • Spring action upon the actuating element is effective between the first end position and an intermediate position and is ineffective between the intermediate position and the second end position.
  • the intermediate position lies between a first and a second end position.
  • the actuating element Since the actuating element is adjusted and held counter to the force of the spring between the first end position and the middle position only, an increased expenditure of energy is necessary only in this actuating range.
  • the motive drive In the actuating range between the middle position and the second end position, the motive drive is necessary only in order to adjust the actuating element, without overcoming a spring force, but not in order to hold the actuating element in position.
  • the actuating drive is switched off, so that only low energy has to be expended for adjustment. No energy at all has to be expended for holding the element in an assumed position.
  • the spring acts only in a partial range of the total range of adjustment between the first and second end position, it can be designed with lower force, as a result of which only a smaller amount of energy is required for the electromotive rotary drive.

  • the electromotive rotary drive may be a direct-current drive.
  • the actuating element may be arranged on a rotatably mounted shaft that can be rotatably driven by the electromotive actuating drive.
  • the shaft has arranged on it, fixedly in terms of rotation, a gearwheel or toothed quadrant which can be rotatably driven by a drive pinion of the electromotive rotary drive directly or via one or more intermediate wheels.
  • a simply construction is achieved in that the first end position is determined by a first limit stop and/or the second end position is determined by a second limit stop. Accordingly, by means of the stops, the rotational movement of the gearwheel or toothed quadrant or of the actuating element or of a component connected to the gearwheel, toothed quadrant or actuating element, can be limited.
  • the ends of the toothed quadrant which are directed in the circumferential direction can be capable of butting up against the first and/or the second limit stop.
  • the stop element may have a driver which can be acted upon by the gearwheel or toothed quadrant in the direction of the first end position, and the stop element may have an intermediate-position stop which, in the intermediate position, is capable of butting up against the intermediate stop in the direction of the second end position.
  • stop element is a stop disk which is mounted freely rotatably on the shaft of the actuating element, only a small amount of installation space is necessary for this simply constructed component.
  • the spring is a spiral spring having one end fixed and another end affixed to the stop element.
  • the spiral spring may act with its one end, in particular with its radially outer end, upon a spring driver of the stop element.
  • an actuating-device housing possesses a bowl-like recess.
  • one end of the shaft projects approximately coaxially.
  • the spiral spring, the stop element, and the gearwheel or toothed quadrant may be arranged in a sandwich-like manner in the bowl-like recess.
  • the actuating-device housing may possess a motor chamber for receiving the electromotive rotary drive.
  • the actuating element may be a rotary slide of a rotary-slide valve.
  • the valve passage may be closed by means of a rotary slide.
  • the slide may be driven rotatably, counter to the force of the spring, out of the closing position and into a partially open position.
  • the slide may further be driven, free of a counterforce, out of the partially open position and into a fully open position.
  • the partially open position may correspond to the intermediate position.
  • one or more further valve passages can be opened and/or can be shut off.
  • a simple construction is obtained when the rotary slide is mounted rotatably in a rotary-slide chamber of the actuating-device housing, and one or more flow inlets and/or flow outlets issuing into the rotary-slide chamber and being capable of being overlapped with one or more flow passages of the rotary slide.
  • the flow inlets and/or flow outlets may issue into the rotary-slide chamber approximately radially and/or-approximately axially.
  • the rotary-slide valve is a regulating valve in a coolant circuit of an internal combustion engine, then, in the event of a failure of the electromotive rotary drive, cooling of the internal combustion engine so as to ensure at least emergency operation is maintained.
  • the maintenance is effectively simply.
  • the coolant circuit as is known in the art, may carry a cooling medium such as engine coolant liquid.
  • the present invention further comprises An actuating device, comprising: an electromotive rotary drive for driving an actuating element about an axis of rotation between a first and a second end position, a spring for acting upon said actuating element in said first end position, wherein said electromotive actuating drive is a reversing drive and said spring action upon said actuating element is effective between said first end position and an intermediate position and is further ineffective between said intermediate position and said second end position, the intermediate position lying between said first and second end position.

  • the rotary slide 3 co rotated via the shaft 8 , is then in a partial opening position, in which the cooling outlet 7 is partially opened, so that cooling liquid can flow to the internal combustion engine and cool the latter.
  • the cooling outlet 7 is to be opened to a lesser extent than the partial opening position, current is supplied to the direct-current motor 26 in such a way that the toothed quadrant 15 moves with its end 22 in the direction of the first limit stop 17 . Since, in this case, the stop disk 14 is taken along by the toothed quadrant 15 via the driver 16 , the spiral spring 10 is also tensioned, so that its force also has to be overcome (see for example FIG. 1 ). This movement leads first to a further closing of the cooling outlet 7 up to the complete shut-off of the latter and to an opening of the short-circuit outlet ( 50 ). When the toothed quadrant 15 is rotated further toward the first limit stop 17 , a shut-off of the short-circuit outlet 6 also takes place ( 40 ).
  • FIG. 3 depicts the various intermediate positions of the regulating valve over the entire range of adjustment 27 of the rotary slide 3 .
